What does the 'Sativa' in Cannabis Sativa L indicate?

The designation 'Sativa' in Cannabis Sativa L refers to its classification as a type of cannabis plant that has specific characteristics suitable for cultivation. This indicates that the plant is cultivated for its psychoactive properties, fibers, seeds, or other beneficial uses.

Cannabis Sativa L is distinguished from other cannabis species primarily based on its growth patterns, height, and the type of effects it typically produces when consumed. Sativa strains are often characterized by their tall, thin leaves and are usually associated with energizing and uplifting effects, which makes them preferable for daytime use.

While the other options relate to aspects of cannabis, they do not specifically capture the significance of 'Sativa' in terms of cultivation. The term does not solely refer to the type of drug, a specific region of growth, or a form of extraction, which means that B is the most accurate choice in this context.
